Tauranga Bridge Marina's dream of a 4 metre high, 245 metre long breakwater structure faces yet another obstacle after two appeals were lodged with the Environment Court.

Last month the company gained temporary resource consent to construct a rock wall breakwater around its northern perimeter to protect the marina in northerly storms and future-proof it from ongoing Port of Tauranga expansion.

The Tauranga Bridge Marina is an existing 11.5 hectare marina located in theTauranga Harbour on reclaimed land adjacent to the northern approach to theTauranga Harbour Bridge.

Bridge Marina proposes building the seawall in two sections. The first section will be a solid rock structure 70m in length, extending from the northern corner of the existing reclamation in a northwest direction towards the Whareroa Channel.

The remainder of the structure will comprise a pile and pre-cast panel structure that will follow the alignment of the existing wave attenuator.

However after the mandatory 15 day working appeal period the company was informed two appeals have been lodged.

Ministry of Justice communications services team leader Antony Paltridge confirms the Environment Court received two appeals, but is unable to comment further. SunLive understands one of the appeals is from Ngati Ranginui.

Bay of Plenty Regional Council senior communications advisor Linda Thompson says because the regional council's decision to grant consent for the seawall has been appealed there is no current consent.

In the regional council's decision released to SunLive, Tauranga Bridge Marina manager Tony Arnold said the purpose of the seawall is to ensure preservation of the existing 500 berth marina facility and for the protection of the marina infrastructure, vessels within and outside the marina, and the public at large.

He says the application is driven by concerns for safety and efficiency.

The marina is currently protected by a 3.6m wide pontoon around the northern extension. It was intended to reduce the wave height within the marina, but it has not performed to expectation.

The next step in the process is Environment Court assisted mediation.
